UNITED STATES PATENT OFFICE.

JOSEPH FROEHLICH, OF NEW YORK, N. Y., ASSIGNOR TO FERDINAND L. SCHMIDT,OF NEW YORK, N. Y.

ENVELOP AND SIMILAR MACHINE.

Specification of Letters Patent.

Application filed July 26, 1909.

To all whom it may concern:

Be it known that I, JOSEPH FRonHLIoH, a citizen of the United States,residing at the borough of Brooklyn, Kings county, city and State of NewYork, have invented certain new and useful Improvements in Envelop andSimilar Machines, of which the following is a specification.

My invention is an improvement of the discharging, ejecting or pushingmechanism usually employed in the folding box of an envelop machine andconsists of continually revolving discharge hooks permitting a greatlyincreased speed of the mechanism used in the process of transferring theenvelop from the folding bed to the drying chain, over the reciprocatingdischarge hooks in use at the present time.

Referring to the drawings Figure l is a longitudinal sectional viewtaken on the cen ter line of an envelop machine and showing the entiremechanism in a position ready to discharge the completely foldedenvelop. Fig. 2 is a plan view of same looking downward from the line 22in Fig. 1. Fig. 3 is a cross section taken on the line 33 of Fig. 1.Figs. 4, 5 and 6 are sectional views similar to Fig. 1 but showing thedifferent positions of the mechanism.

In detail 1 is the plunger shown in its highest position, 2 is acreasing box, 3 is the stationary foundation or folding bed.

4 and 5 are the back and front folders respectively.

7 represents the finished envelop.

8 and 9 are stationary guard plates.

10 are the links of an endless chain running over sprocket shaft 11 andis for the purpose of receiving the enevelop and carrying it away.

12 are the discharge hooks mounted on a continually revolving shaft 13driven by means of the sprockets 14 and 16, and chain 15 from the shaft17.

The shaft 13 is supported by the bearings 19. The sprocket shaft 11 issupported by bearings 18 and has an intermittent motion presenting theopen space 20 ready to receive each envelop.

6 are two side folders.

The folders 4, 5 and 6 are mounted on the able 21 which also supportsthe folding When the plunger 1 has depressed the envelop blank throughthe creasing box 2 and attained the position as shown in Fig. 6 thefolders 4, 5 and 6 are in their extreme vertical position. The plungernow ascends to its highest position, permitting the folders 4, 5 and 6to turn downward and inward as shown in Fig. 4. The folders 4 and 6 nowassume the position shown in Figs. 1 and 3, the front folder 5 raises uphigh enough so that its lower side is somewhat above the top side of thefolding bed 3. The discharge or pushing hooks 12 moving through the slotor opening 23 of the plate 21 and slots 22 of the back folder 4 110wraise up the envelop 7 to the position as shown in Fig. 5 the front endbeing guided underneath the front folder 5 and deflected in a downwarddirection by the guide plate 8. The further movement of the discharge orpushing hooks 12 now pushes the envelop completely off the folding bed.It drops by gravity through the opening in the plate 21 between theguide plates 8 and 9 into the opening 20 of the chain or drier 10 whichnow carries it away and presents a new opening ready to receive anotherenvelop.

IVhat I claim as my invention and desire to secure by Letters Patent is:

1. In an envelop machine, the combination, of a folding bed, a platehaving an opening in suitable proximity to the folding bed and one ormore continuously revolving discharge hooks for pushing the envelop fromthe folding bed into said opening.

2. In an envelop machine, the combination of a folding bed, a platehaving an opening in suitable proximity to the folding bed, one or morecontinuously revolving discharge hooks for pushing the envelop from thefolding bed into said opening and guides forming a channel through whichthe envelop is to pass.

3. In an envelop machine, the combination of a folding bed, a platehaving an opening in suitable proximity to the folding bed, a drier andone or more continuously revolving discharge hooks for pushing theenvelop from the folding bed through said opening into the drier.

4. In an envelop maohine,the combination \Vitnesses F. L. SCHMIDT, E. M.J. KUNZE.
